Rating depth structure for smallmouth bass.

69-acre lake near Paroisse de Beresford. Government of New Brunswick lake depth survey. The lake tops out around 5 ft. The depth chart comes from Government of New Brunswick DNRED bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Lower Tetagouche Lake maps at 69 acres behind 2.4 miles of shoreline. With a 2 development index there's bank structure worth casting at, in moderation. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 0.9 mi, about 0.2 mi across. It sits in Restigouche County. If the bite dies, McRae Lake is 4 mi to the northwest.
Come spring, look for smallmouth bass tight to the bank in 1 to 5 ft. Through summer count on 2 to 5 ft; the winter hold is 2 to 5 ft. If you only fish one area, make it Deep basin: a deep basin around 3 ft that scores good in winter. Best bite is early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft chart-limited; documented 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 2 to 5 ft chart-limited; documented 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 5 ft chart-limited; documented 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 2 to 5 ft chart-limited; documented 20 to 45 ft | midday | Deep basin (3 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: chain pickerel in 1 to 5 ft. The depth story barely changes: 1 to 5 ft through summer, 1 to 5 ft in winter. The spot to know is Deep basin, a deep basin in about 3 ft of water that rates good for chain pickerel in winter. Plan around early morning and the evening in the warm months. Summer baits: a weedless spoon + trailer or a buzzbait gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft chart-limited; documented 2 to 10 ft | midday & dawn | open water | Inline spinner (silver), Small spoon (red/white) |
| Summer | 1 to 5 ft chart-limited; documented 3 to 15 ft | dawn & dusk | open water | Weedless spoon + trailer, Buzzbait |
| Fall | 1 to 5 ft chart-limited; documented 4 to 15 ft | midday & dawn | open water | Jerkbait along weed edges, Spinnerbait |
| Winter | 1 to 5 ft chart-limited; documented 5 to 18 ft | dawn | Deep basin (3 ft) | Jigging spoon (through ice) |
Start shallow in spring: yellow perch sit in 1 to 5 ft that time of year. They don't go far with the seasons — 2 to 5 ft covers summer, 2 to 5 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 3 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.

Spring brook trout on Lower Tetagouche Lake hold shallow, usually 1 to 5 ft. Depth-wise the year is flat: 2 to 5 ft in summer, 1 to 5 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 3 ft, good for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.

Lower Tetagouche Lake is about 5 ft (2 m) deep at its deepest point. The depth chart comes from Government of New Brunswick DNRED bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target smallmouth bass, chain pickerel, yellow perch, brook trout on Lower Tetagouche Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Deep basin is the top-rated area: a deep basin in about 3 ft of water that rates prime for yellow perch in fall. The interactive chart above rates every spot for each species and season.
For smallmouth bass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
